Orchids

There are about 15,000 species of flowering plants on the island of Borneo, around 5,000 of which are endemic (i.e. they aren’t found anywhere else in the world).

And amongst that number are known to be at least 1,700 varieties of orchids (anggrek in Bahasa Indonesia) – with more still being discovered each year.

The Bulbophyllum purpurascens  (above) is one of them… The ‘Purple Bulbophyllum’ (so called because of the colour of its leaves) is found in forests from Myanmar to Java, and it likes to be in a location where the flowers can hang over water. Lovely.

To my delight, I have found that the Kebun Raya Balikpapan (Balikpapan Botanical Gardens) – where I am doing volunteer work this year – houses a wonderful collection of orchids – in the newly constructed Rumah Anggrek (Orchid House). It’s so new that it’s not yet fitted out – or open to visitors.

There are different orchids blooming throughout the year, so every week there are new ones to see. And such variety – of colours, forms, and … ‘personalities’.

To my further delight, one of my tasks here is to compile a comprehensive photographic catalogue of every orchid as they flower during the year 2017. Talk about a labour of love…

The collection (of nearly 500 species) is meticulously cared for by Micha (Micha Juwari) and Jupri (Jufrianto). Their detailed knowledge of the plants is very impressive, as is their obvious love for the (often fragile and fussy) orchids in their care. They found and collected many of the plants themselves in the course of various expeditions – to remote areas like the forests around Berau, as well as in the Sungai Wain Protected Forest which is immediately adjacent to the Kebun Raya.

So, here are just some of the highlights from my first five weeks…

WEEK 1

Phalaenopsis cornu-cervi (Breda) Blume & Rchb.f. The ‘Deer Antlered Phalaenopsis’. Like many orchids, it’s an ‘epiphyte’ – meaning that it grows on another host plant rather than in the ground, but only for support i.e. it’s not parasitic. It gets its nutrients from the air and dust, and its water from rain. It is a local plant, having been collected from the Sungai Wain Protected Forest just adjacent to the Kebun Raya.

This very striking flower is about four centimetres across. There are two other varieties – one has purely yellow petals, and one is entirely red. I’ve only seen them in photographs – but I think I prefer the contrast of having both colours together.

Dendrobium secundum (Blume). It’s also known as the ‘Toothbrush orchid’ because the shape of the flower head bears a passing resemblance to a toothbrush. However, toothpaste does not adhere well to the blooms, which are too large to fit comfortably inside one’s mouth, and the ‘brush’ is pretty much ruined after a single use.

Thelasis carinata Blume. The ‘Keeled Thelasis’ is found from Myanmar right across Southeast Asia, through PNG and to the Solomon Islands. It’s even found in Far North Queensland, where it’s known as the ‘Triangular Fly Orchid’.

Like a large percentage of the wild orchids, the flowers of this species are quite small, the big ones only around 0.5 cm long. The macro lens makes them seem a lot bigger in the photo above.

Dipodium paludosum (Griff.) Rchb.f. This gorgeous orchid is much larger than most, with each flower around 4cm across.

This one was collected from the Gunung Ketam protected forest, west of here, near the border between East and Central Kalimantan provinces.

WEEK 2

Coelogyne pandurata Lindl. This stunning and most unusual orchid is famous as the ‘Black Orchid’, although in truth it is mostly a striking hue of greeny yellow. The rich black patterns on the ‘lip’ of the flower are however quite dramatic. It grows locally in the Sungai Wain Protected Forest.

The large flowers have a surprising honey-sweet smell. They only last for a few days, but the plant can flower two (or more) times in one year.

There’s a bit of interesting history about Hugh Low, the European ‘discoverer’ of this orchid (in 1853) here.

WEEK 3

Eria nutans Lindl. – ‘The Nodding Eria’. This epiphyte is found in Malaysia, Thailand, Sumatra as well as in Borneo. I really liked its shy and gracefully pendulous, solitary little flower. Not at all showy, like some of the big prolific orchids – but quite lovely and delicate.

Cymbidium bicolor. This epiphyte is popular with collectors and home gardeners because, apart from being big (with 4 – 7cm blooms), prolific and splashy, it’s also quite hardy. The dangling flower stem can be up to 70cm long, and with as many as two dozen blooms on it.

Bulbophyllum vaginatum – ‘The Vagina Bulbophyllum’. No I don’t know how it got that name.

Apparently, in Java, the tiny fruits of this orchid are boiled up with fruits from some other orchids, and used as a treatment for earache.

WEEK 4

This lovely orchid is labelled as ‘Acriopsis sp.’. The name ‘Acriopsis‘ comes from Greek, and means it ‘resembles a locust’ – but I can’t see the resemblance myself…

The nine species in the Acriopsis genus are known as the ‘Chandelier Orchids’, and are native to various lowland forest locations from Assam to Queensland.‘Acriopsis’ is the genus, and the ‘sp.’ bit means that the precise species hasn’t yet been officially determined.

My confident Google-based opinion is that it is actually an ‘Acriopsis ridleyi Hook.f.’, ‘Ridley’s Orchid’ which is endemic to Borneo and Malaysia.

I love the language that orchid specialists (and other botanists) use to describe their subjects. Surely their vocabulary is incomprehensible to anyone outside their specialIst field? For example, see this description (from Flora of China) of the Pomatocalpa spicatum (pictured above):

“Stems erect, 2-3 cm, stout. Leaves 5 or 6; leaf blade dark green, broadly lorate or falcate-oblong, 20-31 × 2.5-3.5 cm, leathery, margin ± undulate, apex unequally bilobed. Inflorescences 2 or 3, lateral, pendulous, 3.5-6 cm, unbranched and racemose or occasionally with 1 or 2 branches; rachis fleshy, ribbed, densely many flowered; floral bracts reflexed, broadly ovate-triangular, ca. 1 mm, acute, often adnate to rachis. Flowers waxy yellow, rather fleshy, dorsal sepal with 2 brown bands at base, lateral sepals with U-shaped brown spots at base and with 2 brown bands above middle, petals with 2 brown bands at base; pedicel and ovary ca. 2.5 mm. Dorsal sepal obovate, ca. 5 × 2 mm, apex rounded; lateral sepals incurved, slightly obliquely obovate, ca. 4.5 × 2.5 mm, obtuse-rounded. Petals obovate-elliptic, ca. 3 × 1.8 mm, obtuse; lip spurred at base, 3-lobed; lateral lobes erect, ovate; mid-lobe reniform-triangular or subrhombic, ca. 1.5 × 1.5 mm, fleshy, apex obtuse; spur subglobose, ca. 2 × 2 mm, inside with a ligulate bilobed-tipped appendage on back wall and a pair of calli near base of disk. Column ca. 2 mm; rostellum ovate-triangular, ca. 0.4 mm; stipe ca. 1.2 mm, narrow; viscidium ca. 0.5 mm, subelliptic, one end broadly emarginate. Fl. Apr. 2n = 38.”

No doubt that it is an accurate description, but it fails to do justice to the sheer beauty of the flower!

Thecostele alata (’The Winged Thecostele’), a lovely orchid which can be found from Northeastern India across to The Philippines, including East Kalimantan, where this one was collected for the Koleksi Anggrek (Orchid Collection). The individual blooms don’t last for many days, but they open successively, so they can continue to bloom for weeks or months.

For those who care about these things, it’s a ‘monotype’ i.e. it’s (currently) the only species in the genus Thecostele.

Bulbophyllum odoratum – ‘The Scented Bulbophyllum’. Here’s some useful trivia: this plant is just one member of the genera Bulbophyllum which, with over 2,000 species, is the second largest of all flowering plants. There’s over 600 Bulbophyllum species in PNG alone! The members of Bulbophyllum can be readily identified because of the “single-noded pseudobulbs, the basal inflorescence and the mobile lip”. Look out for that.

WEEK 5

Dendrobium anosmum. This highly fragrant orchid is curiously named ‘anosmum’ – which means ‘without scent’. I like it better by its synonym ‘Dendrobium superbum’ – a name it was given because it is ‘superb’ – not in reference to its smell.

In Hawaii, where it is known as honohono, it is often used in the making of leis.

Dendrobium sanguinolentum – (The Blood-stained Dendrobium). There appears to be a couple of colour variations of this species, with one having flowers that are entirely pale yellow in colour. The ’standard’ ones have a little patch of crimson red on the tips of each petal, hence the ‘blood-stained’ name.

Calanthe sp. The ‘sp.’ in the name means that the Kebun Raya hasn’t yet obtained a definitive determination of which species it is within the Calanthe genus. There are over 200 species of Calanthe, distributed almost worldwide.

This one opens up to form a large spray of white flowers, but I actually like it even better before the ‘bulb’ of flowers opens up. Elegant shape, full of life, vitality and potential.

Acriopsis liliifolia. Another Acriopsis (‘Chandelier Orchids’), this one definitively identified as the liliifolia species – the ‘Lily-leaved Acriopsis’). It’s a lowland orchid, likes damp places, and blooms prolifically. The flower-stalks may branch several times, and have up to 200 flowers. Perfect dainty little blossoms.

500 metres per hour…

If you take a short cut through the forest, it’s only about 500 metres’ walk from the Visitor Centre at the Kebun Raya Balikpapan to the Orchid House (Rumah Anggrek).

But this morning it took me nearly an hour. There were lots of distractions along the way…

Forest floor

I spend a lot of time at the Kebun Raya Balikpapan looking upwards, craning my neck to see birds, monkeys, fruit, flowers and treetops in the forest canopy.

But the ground below is sometimes uneven, and very often slippery, so I also spend a lot of time looking down at the forest floor. Sometimes that view is every bit as interesting!

Owa wa

Hylobates muelleri‘ is known in English as ‘Mueller’s Bornean Gibbon’. But I much prefer the Indonesian name ‘Owa wa‘, which is a near-exact transcription of this gibbon’s distinctive call.

This primate is endemic to the island of Borneo. It’s classed as ‘endangered’ – mostly because of the continuing loss of its forest habitat.

I saw this one (an adult female) this morning at the Kebun Raya Balikpapan. She was a little distant, and I had to photograph her through the branches and foliage of another tree. Hopefully there’ll be more opportunities to see, hear and photograph Owa wa before the year is out.

Lutung merah

The Lutung Merah (Presbytis rubicunda) is variously known in English as the maroon langur, maroon leaf monkey, or red leaf monkey. It’s unique to Borneo and the neighbouring little island of Karimata. They eat leaves, fruit and seeds. Their bodies only grow to 60cm – but with an extra 80cm of tail attached. Although their range is limited, the species is not (currently) regarded as ‘threatened’.

There certainly seems to be quite a few of them at the Kebun Raya Balikpapan, even close to the visitor centre. I’m told that they are just one of 12 species of primates which live in the local forest.

Anggrek du jour – Thecostele alata

KRB_Anggrek_20170123_058
Thecostele alata, a lovely terrestrial orchid which can be found from Northeastern India across to The Philippines, including East Kalimantan, where this one was collected for the Koleksi Anggrek (Orchid Collection) at the Kebun Raya Balikpapan (Balikpapan Botanical Garden).

I photographed this one just yesterday. Every week there are new and different orchids in bloom. Yesterday there were 13 new ones!

KRB_Anggrek_20170123_055

For those who care about these things, it’s (currently) the only species in the genus Thecostele.

Anak burung, Pak John!

I was making some photos in the ‘Belian Garden’ (medicinal plants) at the Kebun Raya Balikpapan (Balikpapan Botanical Gardens), when one of my workmates beckoned me over to show a perfect little bird’s nest hidden inside one of the bushes. “Anak burung, Pak John!” The two tiny little featherless things hadn’t even opened their eyes.

KRB_orientasi_20170105_055

He said the parents were out getting food, and sure enough, in a nearby tree was a ‘Karuang‘ (Sooty-headed bulbul, Pycnonotus aurigaster), with some tasty morsel in its beak, anxiously waiting for us to go away from the imperfectly-hidden nest.

KRB_macro_20170109_028

I checked on the chicks’ development over the next week, and it was amazing how quickly they transformed into something more recognisably birdlike. But, two days ago, the nest was empty. No sign of any violence (e.g. from a cat), but surely they weren’t big enough to fly independently, so I fear the worst for them….

The Pemulung of Piyungan

As part of our most recent month of training in Indonesian language and culture at the Wisma Bahasa school in Jogjakarta, we got to go on two half-day ‘field trips’. Because we had already been all the ‘standard’ tours on offer at least once (the Kraton, Borobodur, Prambanan, Pasar Beringhardjo, Kota Gede, Imogiri etc) we were asked where else we’d like to go.

jogjakarta_tpa_20161215_016

So (of course!) we nominated the Tempat Pembuangan Akhir (TPA) – the local garbage disposal facility and landfill site. After some efforts to dissuade us (“It smells REALLY bad!, you know” “It’s muddy, filthy, and unsanitary!” “You’ll need to wear a mask”) it was agreed, and Mas Anof kindly consented to accompany us there.

jogjakarta_tpa_20161215_001

The TPA has been in operation near the village of Piyungan, about 16km southeast from central Jogja, since 1995. The site, which covers 13 hectares, is the final site of waste disposal for the city of Jogjakarta, as well as the adjacent Kabupaten (districts) of Bantul and Sleman.

It was constructed in three stages, with a total planned capacity of some 1,300,000 cubic metres. That’s a big heap of garbage. Due to the sheer volume of accumulated waste at the site, and also because of its location amongst some (rather scenic) limestone karst formations, it’s known as the ‘Gunung Sampah’ (the ‘Garbage Mountain’).

jogjakarta_tpa_20161215_005

In addition to the many people who live and work in the area, the TPA is home to hundreds of cattle, who feast on the waste vegetable matter, leaves and tree prunings that get dumped there. They roam freely over the site, and are remarkably healthy-looking – considering their diet and habitat. They are owned by the families who live and work at the site.

One owner told me that they sell the meat from the cattle at the public markets. We were instantly attracted to vegetarianism.

jogjakarta_tpa_20161215_024

People and cattle mingle freely across the site, seemingly oblivious to each others presence.

jogjakarta_tpa_20161215_063

A steady procession of trucks and utilities arrive, each loaded to the brim (and above) with garbage.

jogjakarta_tpa_20161215_089

As each load is dumped, groups of workers arrive to sort through the load, looking for bottles, recyclable plastic and paper – and anything else that might be of value. They are usually referred to as pemulung (scavengers), but it may be more respectful to call them pengumpul barang bekas (collectors of used goods).

I don’t know how many pemulung currently work at the TPA – but back in 2007 there were 225.

jogjakarta_tpa_20161215_077

They only get paid for what they collect, so they work with speed and efficiency, without a lot of ‘workplace chatter’. There are roughly equal numbers of men and women, and (pleasingly) we didn’t see any children. Most of them wear the conical Javanese ‘caping’ hat as protection from sun and rain, and most are very sensibly kitted out in gumboots. Many wear gloves, but all carry a short pole with a hook on the end to pick up recyclable plastic and paper, which is then dropped into a large bamboo basket.

jogjakarta_tpa_20161215_065

Each pemulung gives her or his collected stuff each week to a particular ‘skipper’ (juragan), each of whom may ‘oversee’ between 10 and 20 pemulung. The juragan recruits the workers, many of whom come from Pantai Baronan, on the far east coast of the Jogjakarta region.

 

jogjakarta_tpa_20161215_105We were told that a good pemulung can make a ‘reasonable’ amount of money in a day, enough that they don’t have to work every day to get enough for subsistence living. And if you didn’t have to work there every day – why would you?

We found out later that they can earn around Rp600,000 to Rp700,000 per month (around AU$70 – just over $2 per day). That’s if they are fit and healthy, which is not always the case.

jogjakarta_tpa_20161215_099

There is no sick leave, superannuation or holiday pay. Possessing no capital resources, little or no formal education, and no control over the prices they are paid for their work, they have little or no opportunity to escape from this workplace.

The work is also dangerous. On 21 February 2005, an ‘avalanche’ at the another landfill site (Leuwigajah, near Bandung), buried 71 houses and killed some 143 pemulung and others at the site.

jogjakarta_tpa_20161215_040

At first we were quite reticent about photographing the people at work, thinking that they might feel shamed or disrespected by being pictured doing such a dirty and menial activity. The negative connotations of ‘poverty porn’ came to mind.

jogjakarta_tpa_20161215_018

But no-one declined when asked to be photographed, and some seemed to rather enjoy the attention.

jogjakarta_tpa_20161215_050

Mostly, though, everyone was so focussed on their work that they largely ignored us, apart from responding to the usual greetings, and asking the ‘where-are-you-from’ type questions.

jogjakarta_tpa_20161215_108

The pemulung actually provide an important service. It’s estimated that 20-30% of the waste dumped at the TPA is recycled (including that portion which is eaten by the cattle). Without this reduction to the volume of waste the landfill would have exceeded capacity several years ago.

jogjakarta_tpa_20161215_057

It’s good to see what happens to our waste after we throw it out, and it was a fascinating, shocking, thought-provoking, outrage-inducing experience to visit the Jogja TPA. And yes, it is a smelly place, and our clothes (and especially shoes) needed professional cleaning before they could be worn again.
